An optimization-simulation approach for long term care structure assignment problem for elderly people

The growing number of elderly people is one of the most important problems for the next years. This part of the population is often dependent and does not tolerate environment changes so that long term care structure assignment should be well prepared. This paper proposes a new optimization-simulation approach to (i) solve the long term care structure assignment problem for a population of elderly people and (ii) validate and calibrate the model depending on stakeholders objectives and territory special features. A Mixed-Integer Linear Program is proposed to solve the tactical assignment problem, while a stochastic simulation is used to assess the key performance indicators relevant for elderly on the long term.
